“…LCA studies of nutrient removal are of particular relevance. Several studies have evaluated the comparative impacts of different degrees of nutrient removal; ,, however, they predominantly evaluated secondary processes and focused on energy use, eutrophication, and GHG emissions, while other categories of environmental impact were not considered. Foley et al conducted a comprehensive life-cycle inventory study of nine different treatment cases that were focused on achieving different effluent N and P levels.…”

Advanced nutrient removal processes, while improving the water quality of the receiving water body, can also produce indirect environmental and health impacts associated with increases in usage of energy, chemicals, and other material resources. The present study evaluated three levels of treatment for nutrient removal (N and P) using 27 representative treatment process configurations. Impacts were assessed across multiple environmental and health impacts using life-cycle assessment (LCA) following the Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) impact-assessment method. Results show that advanced technologies that achieve high-level nutrient removal significantly decreased local eutrophication potential, while chemicals and electricity use for these advanced treatments, particularly multistage enhanced tertiary processes and reverse osmosis, simultaneously increased eutrophication indirectly and contributed to other potential environmental and health impacts including human and ecotoxicity, global warming potential, ozone depletion, and acidification. Average eutrophication potential can be reduced by about 70% when Level 2 (TN = 3 mg/L; TP = 0.1 mg/L) treatments are employed instead of Level 1 (TN = 8 mg/L; TP = 1 mg/L), but the implementation of more advanced tertiary processes for Level 3 (TN = 1 mg/L; TP = 0.01 mg/L) treatment may only lead to an additional 15% net reduction in life-cycle eutrophication potential.

“…Mounting sustainability impacts associated with higher levels of phosphorus removal have been reported by Falk et al (2011), showing order of magnitude increases in the GHG emissions ratio to the mass of phosphorus removed at higher treatment levels. This factor generally dissuades consideration of RO as a sustainable approach to phosphorus removal.…”

A one-year Demonstration Study conducted by the Regional Municipality of York (York Region) demonstrated the ability of membrane technology including microfiltration (MF) and reverse osmosis (RO) following biological treatment of municipal wastewater to consistently and reliably achieve an ultra-low total phosphorus (TP) concentration of less than 20 micrograms phosphorus per liter (µg P/L). The study provided valuable data and operational insight which was previously unavailable. Key design and operational parameters of the membrane systems included flux, recovery, normalized permeability, chemical usage, and backwash/cleaning regimes and frequencies. The majority of TP concentrations in MF permeate samples were less than 40 µg/L, and TP concentrations in approximately 70 percent of the RO permeate samples were reported as less than the Method Detection Limit of 2 µg/L.While the sustainability case for advanced treatment is unique to the project circumstances, York Region's Demonstration Study of MF and RO helps to advance all aspects of the Region's preferred alternative for wastewater servicing. In addition to use of advanced treatment processes to produce an ultra-low TP concentration, the preferred alternative includes alternative methods to reduce phosphorus loading such as water reuse and project-specific phosphorus offsets.
